A week after the collapse of Mt.Gox, Japan is still struggling to craft a response to the bitcoin phenomenon, saying the crypto-currency is not legal tender, though it might be taxable and subject to money-laundering controls.

In its first detailed response to the bankruptcy of the Tokyo-based company, once the world’s biggest bitcoin exchange, the government issued a statement assessing how bitcoin is covered – or more often, not covered – by existing law.

The issue took on new prominence in Japan on February 28, when Mt.Gox sought Chapter 11-style bankruptcy protection, saying it had lost bitcoins and cash worth some half a billion dollars due to hacker attacks.

Bitcoin is not a currency, but could be taxable under some circumstances, the statement says. Although the government understands that bitcoin is not issued or backed by any government or central bank, “we have not grasped the situation in its entirety."

The authorities are monitoring the Mt.Gox bankruptcy process and, if necessary, will consider a response, said chief cabinet secretary
Yoshihide Suga

Trouble with bitcoins

Fewer than 1 per cent of Mt.Gox’s 127,000 creditors are Japanese, the company has said. Yet across the government, officials are wrestling with how to handle bitcoin.

“It’s not money," said Finance Minister
Taro Aso
. “Does the Financial Services Agency have jurisdiction? The Finance Ministry? The Consumer Affairs Agency? The Ministry of Economy, Trade and Industry?" he asked at a regular news conference. “Opinions are divided."

The government statement, citing 18 sections of 11 laws and regulations, says bitcoin is not a currency or an asset within the purview of professional trading or asset management, while trading the virtual currency is not a banking or financial-instrument transaction.

But, generally speaking, bitcoin could be taxable if it meets certain conditions of income, corporate or consumption tax laws, the statement says. This leaves open the possibility that bitcoin could be treated as a commodity like gold, although the statement does not specify this.

Regarding money laundering, certain transactions – whether with bitcoin or not – require people to identify themselves, it notes.
